I Thisinvention relates to improvements in commercial photographicprinting apparatus and more particularly to the means used in securing avariety of plates in predetermined relative positions within framessubject to transference to a machine for the printing operation.

The word plate is used broadlyto includ both positive and negativeelements, the term negative referring to either a rigid or flexibleplate, film or the like, made of any transparent or translucentmaterial, as glass, celluloid or similar substance, paper'or textilefabrics treated to permit the passage of light, and bearing images orlegends, inscribed manually or mechanically, or depositedphotographically, ofv any subject matter, or having objects attached ina manner to be reproduced by photo-printing.

A positive is to be construed as a receptive element of correspondingnature, sensitized to receive a photographic image from a negative heldin juxtaposition and subjected to actinic light.

One of the objects of the invention is to provide a frame havingdistinct and wholly inde- 25 pendent portions, each suited to receive aseparate negative bearing registering marks and having means whereby theportions of the frame are relatively movable, in the same plane, bothrectilinearly and transversely, that is vertically and horizontally withrespect to an upright machine, and also angularly, whereby the registermarks on each portion may be brought into absolute correspondence withregister marks fixed on amaster frame superposed on portions of thenegative carrying frame.

A further feature is in the provision of means for transferring thenegative frame to a holder having connection with asuction means forproducing a partial vacuum and provided with a marginal seal, the holderand irame being transferable as a unit to a registration plate havingmeans for adjusting the unit in accordance with marks fixed upon it andthereafter held fixedly by clamp dowel engaging arms, carried by theunit, so that the unit may be placed in exact correspondence upon dowelson the face of a photo-printing machine.

Other objects, such as direct and positive shown in the accompanyingdrawings, constituting a material part of this disclosure, and in which:

Figure l is a top planview of a two part plate holder frame providedwith means for adjusting one part relative to the other, both partshaving plate receiving recesses, and means for confining plates therein,each plate being provided with registry marks.

Figure 2 is a similar view of a master frame having clamping means toengage the plate holder frame when superposed, and provided with fixedregistry lines to which the parts of the plate holder are adjusted. i

Figure 3 is a plan view of, a holder apertured in conformity with theopenings in the plate holder frame, part of one of which is shown asseated on a sealing blanket resting onthe holder which is provided withclamping means and extending adjustable arms. 5

- Figure 4 is a similar plan view of the same parts as disposed on atransfer plate having means for adjusting the frame and holder to agreewith marks arranged in known relation to a photoprinting machineprovided with dowels to engage openings in the holder armswhich areclamped when registration has been effected. 1

Fig. 3.

Figure 9 is a plan view of a device as seen in Fig. 8 but showing amodified plate adjusting, means.

Figure 10 is a similar view of the same parts as mounted on a transferplate. Y

Figure 11 is an enlarged cross sectional View taken through one of thenon-metallic clamps as disposed within the confines of a sealing device.

The devices shownin either Figs. 1 and 7 are composed of twosubstantially like frames 15 and. 16 provided with continuous. recesses15'16' suited to receive plates Hand 18 bearing registry marks 19,20 andl9'20, at their respective side, and end edges, these plates beingsecurely held in the frames by clamps 21, disposed preferably atOpposite corners and set at least flush with the faces of the frame.

Extending from the side of the frame 15, near its'ends, towards theframe 16; are a pair of lugs 23, and rigidly attached to the adjacentmember of the frame 16 is a bar 24 reaching outwardly beyond the frameat each end both of which are slotted to receive sleeves 25 pivoted onthe points of opposed screws 26 set in the bar ends.

Passing freely through the sleeves 25 are the plain cylindrical portionsof adjusting screws 27 having flanged operative heads 27 and fixedcollars 28 at the opposite ends of the sleeves, while the threadedportions of the screws engage in blocks 29. v

Also passing through the blocks 29 are the unthreaded end portions of ascrew 30 screwthre'adedly engaging the lugs 23, the screw having anoperating knob 30 by which it may be rotated.

From the foregoing it will be manifest that the frames 15--16 may bepositively moved to a limited amount towards and from each other,

whether in parallelism or at moderate angles, and furthermore the framesmay be shifted relatively frame 35, the same being engageable by studs31 set in the ends of the frame 16, which after having been tightened,permit shifting of the frame 15, by the means herein described, to causeregistration of the marks 20 with the line 3'7 and the marks 19 with thelines 36.

After the marks and lines have been brought in perfect registration, theframe 35 is removed, the frames 15-16 are placed upon a transfer platehaving openings 4141 conforming generally to the frame openings.

Disposed intermediate the registered frames 15-16 and surface of theplate 40 is yielding element 42, such as a rubber blanket having slots43. through which may bepassed clamping means, as the hooks 44 pivotedin recesses in the plate 40 on pins 45, these hooks being engageablewith the frame projections 31-31', as seen in Figs. 3, 4' and 8 and indetail in Fig. 6.

The plate 40, which may be considered as a transfer element, is providedwith perforations 46 in its end portions, adjacent to which are slots 47to adjustably receive bolts 48 by which adjustable arms 49 may besecurely clamped in position.

Perforations 50 in the arms are engageable with dowels 51 set in a plate52 and also with exactly similar dowels set in the face of the machineto which the previously described devices ;are transferable.

' The plate 52 is provided with cross marks 5354 and operative devices,as indicated by the arms 55 engageable in the openings 46 to bring theelements into exact registration thence to be clamped by the bolts 48.

A series of studs 56, adjustable on the plate 52, provide means forlevelling and supporting the plate 40 during adjustment and a marginalseal 57' encloses the space between the plates .-2 40-42, the spacebeing served by a suction tube 58 whereby a partial vacuum may beproduced between the plates 40-42.

In Figures 7 and 8 the construction is essentially the same as depictedin Figs. 1 and 3 with respect to the frames and their relative adjustingdevices, but in the modification the frames are disposed on an aperturedplate 60 and each frame is provided with a border seal 61-61 the spacesbetween being served by suction tubes 6262 to produce a vacuum.

Figs. 9 and 10 disclose one of the negative plates 65 clamped in a fixedposition and theother plate 65 provided with set screws 6? adjustable inlugs 68 upstanding from an apertured plate 69 by which the plate mayobviously be moved into as many different positions as the plate 17 withwhich it agrees in registration marks.

Figure 10 shows the plate 69 as having a marginal seal '70 interposedbetween it and an aper-. tured plate '71, the enclosed space havingleading into it a suction tube 72 by which a vacuum may. be produced. v1

The preferred form of space sealing means is well indicated in Fig. 11,but is not to be understood in a limiting sense. i

A partial section of a plate support frame 75 is formed with aninreaching lip, in which may be set a thin light sealing element 76 uponwhich the marginal edges of the plate 78 are seated.

The edges of the plate are bevelled and held firmly on the frame by aplurality of non-metallic clips 80, such for instance as induratedfiber, hard rubber, or any of the phenol resins, tough, firm andslightly elastic when drawn into engagement by the clamp screws '79.

These clips are slightly thinner than the plate 78 and outwardly, beyondtheir opposite edge is a circurnambient space 81 surrounded by a sealingmember 82 on which another plate may be seated and drawn into desiredintimate relation with the plate 75 by producing a vacuum in the space81.

'Although the foregoing is descriptive of the preferred embodiment ofthe sealing means, inclusive of the clips and sealing member, it is tobe understood that the invention is not confined to the exact structureshown and described, as equivalent devices of widely variant nature maybe substituted therefor.

The foregoing disclosure-is to be regarded as descriptive andillustrative only, and not as restrictive or limitative of theinvention, of which obviously an embodiment may be constructed ineludingmany modifications without departing from the general scope hereinindicated and denoted in the appended claims.
